The demonstration we require is always necessary when the superiority of the means propounded is not so evident as to leave no room for doubt, and it consists in the examination of each of the means on its own merits, and then of its comparison with the object desired.  When once the thing is traced back to a simple truth, controversy must cease, or at all events a new result is obtained, whilst by the other plan the pros and cons go on for ever consuming each other.

Should we, for example, not rest content with assertion in the case before mentioned, and wish to prove that the persistent pursuit of Bluecher would have been more advantageous than the turning on Schwartzenberg, we should support the arguments on the following simple truths: 

1.  In general it is more advantageous to continue our blows in one and the same direction, because there is a loss of time in striking in different directions; and at a point where the moral power is already shaken by considerable losses there is the more reason to expect fresh successes, therefore in that way no part of the preponderance already gained is left idle.

2.  Because Bluecher, although weaker than Schwartzenberg, was, on account of his enterprising spirit, the more important adversary; in him, therefore, lay the centre of attraction which drew the others along in the same direction.

3.  Because the losses which Bluecher had sustained almost amounted to a defeat, which gave Buonaparte such a preponderance over him as to make his retreat to the Rhine almost certain, and at the same time no reserves of any consequence awaited him there.

4.  Because there was no other result which would be so terrific in its aspects, would appear to the imagination in such gigantic proportions, an immense advantage in dealing with a Staff so weak and irresolute as that of Schwartzenberg notoriously was at this time.  What had happened to the Crown Prince of Wartemberg at Montereau, and to Count Wittgenstein at Mormant, Prince Schwartzenberg must have known well enough; but all the untoward events on Bluecher’s distant and separate line from the Marne to the Rhine would only reach him by the avalanche of rumour.  The desperate movements which Buonaparte made upon Vitry at the end of March, to see what the Allies would do if he threatened to turn them strategically, were evidently done on the principle of working on their fears; but it was done under far different circumstances, in consequence of his defeat at Laon and Arcis, and because Bluecher, with 100,000 men, was then in communication with Schwartzenberg.

There are people, no doubt, who will not be convinced on these arguments, but at all events they cannot retort by saying, that “whilst Buonaparte threatened Schwartzenberg’s base by advancing to the Rhine, Schwartzenberg at the same time threatened Buonaparte’s communications with Paris,” because we have shown by the reasons above given that Schwartzenberg would never have thought of marching on Paris.
